This Laser Radio Transmitter Could Be The Key To Ultra Fast Wi-Fi

Cellular data and Wi-Fi traffic are growing at an exponential pace, so is the need to increase the capacity of wireless links. Unless we find a way to accomplish it, the rising traffic is bound to lead to unmanagable bottlenecks. Taking this thought forward, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences […]

Bell Says Transmitter Updates on April 28 Will Affect Free Over-the-Air CTV Channels

Bell says the federal government is set to make transmitter updates, which will affect those using over-the-air and rooftop antennas for TV signals. The change is being made to free up spectrum for wireless usage.

The change will come after 12 midnight on April 28, 2019, says Bell, and will affect the following channels:

  • CTV Toronto’s Channel 9.1
  • CTV Victoria’s Channel 23. 1
  • CTV Windsor’s Channel 26.1

In order to keep watching your over-the-air television on these channels, you will need to re-scan your television or third-party app, which takes a few minutes to complete.

Bell explains ^(, “Mandated by ISED (Innovation, Science, and Economic Development)  in Canada and the Federal Communications Commission in the U.S. (FCC), this “TV channel repack” program requires broadcasters with over-the-air services to transition into a tighter spectrum to free up more spectrum for wireless carriers.”

For Canadians looking to get free over-the-air television signals, all you need is an HD antenna, available via Amazon ^(

Along with a SiliconDust HDHomeRun Connect unit ^(, you’ll be able to stream live television over your Wi-Fi network to other devices, and when setup with a Plex Pass ^(, you’ll have full PVR capabilities. You can also watch on Apple TV with the Plex or InstaTV tvOS apps.

We’ve tried this setup before and it works great for limited channels, such as CTV, CBC and Global in HD, for example.
